T0 (d6 whom it may concern:

Be it known that I Janus I. RICHEY, a citizen of the United btates of America, and a resident of Cincinnati, in the county of Hamilton and State of Ohio, have invented a certain new and useful lm n'ovement in Manifold-Heaters, of which the following is a s )ecification.

his invention relates to a handy auxiliary or accessory device that is appli 'able to the convenient speedy-warming or heating of the manifold or inlet-pipe'of an internalcombustion engine for autoinol. ilcs or the like prior to the passage or entrance of the gases into the cylinders thereof, especially in cold weather and just before the starting of the machine, and its object is to provide an independent, open-top cup or receptacle for containing a warm or hot medium such as water, sand, or the lilce that is poured into said open-top cup, and which cup is adapted to be readily slipped on the upturned elbow of the ordinary manifold and to contain the latter inunerscd within the heated medium so that the gases passing through said mani fold shall be pre'heatcd before entering tln engine cylinders or the comlmstion-chamliersand thereby facilitating the immediate or prompt starting-operation of the engine, the gases being thus more readily and speedily ignited and exploded and. also, more easily maintained so during the further operation of the machine. The machine can thus be started more expeditiously and cllicicntly, especially, but not essentially, during cool or very cold weather.

pointed out in the claim that follows.

In the accompanying sheet of drawings,- ligure l is a pcrspm-tlvc view of the warming detachable, open-top i-up or rm-cptacle that is adapted .to contain the manifold or intake and its pre-hcatingmedium. and cmbot lying the preferred form of my invention herein; Fig. 2, a fragmentary perspective of parts of an internalcombustion engine adjacent to and associated with the manifold or inlet-pipe, showing my auxiliary cup or receptacle for containing said manifold and a pro-heating medium therefor; Fig. Zha central longitudinal section of Fig. l. but containing the manifold that is shown immersed in the pro-heating medium; and Fig. 4, a detail pers )ective of the split band or clamping-ring shown immediately below Fig. l.

he details of structure will be fullyherc matter described and then more particularly and used for tightly coupling the lower eontracted neck of the said cap in place on the upturned inlet-elhon of. the manifold.

l indicates the gasexplosive part of the shell of the engine, having the usual exhaustpipe 2 and spark-plugs 4 indicates the usual manifold orinlet pipe havinga lower gas inlet'elbow 5 and controlling devices 6.

7 indicates each of the customary retentiou-stirrnps used for supporting the mani' fold in place.

8 indicates an elongated tapering cup or receptacle. made of sheet-metal or any other suitable material, and provided with a narrow neck or contracted flange or extension J at its lower portionl This cup is prefer ably split or left open vertically at one end thereof, as shown at It), and a thin strip of leather. rubber, or other similar material 1]. is used to line or pack the lap-joint that is formed by the opposite ends of the cup material in its vertically'split portion. The said strip ll may be used or not as desired in the joint, and screw-bolts 12 areprovidcd to draw the joint firm and tight against leakage. It is not altogether essential, however, that the cup be made watertight except to hold the heating-medium therein long enough to warm or heat the manifold to the desired degree, that would pot l'tPt'lllll'fl more than a minute or two and lcpem cut on the coldness of the weather otherwise.

Instead of makin the joint as shown so that it may be read! v thrown open and the device readily slipper endwise and attached;

into place or removed from such place, sai joint may be soldered or made entirely closed and thus not permitting the cup to be readily placed on the manifold or removed therefrom, which latter feature is not really essential, although somewhat de sirable, in the extended use of the machine on which the device is mounted.

A lid or cap (not shown) may be used on the cup for retaining the heat therein, or preventing the entrance of foreign matter.

A detachable clamping-ring 13 is providcd on the contracted lower end or neck 9 of thew-up for securely attaching it in place on the upturned inlet-elbow 5 of the manifold. I

Vertical ii vcrtcd U-shapc loops l-lare also provided to further support the cup in suspended place, from the exhaust-pipe 2, the

lower twiated and hook end 1:") and 15*, respectively, ol' the loop engaging holes It; in the upper edges of the longitudinal sideu 0f the eup and easily detael'iahle when neressary.

17 indicates a drain or draw-oil cork mounted in the lower portion of the cup for readily emptying the latter when desired.

Hot water, sand, or other medium is, provided in the cup when it is desired to 'arm the manifold and preheat the gahes paint therethrough before starting, or at the time of starting the machine. and tllerehy speed or expedite the prompt and positive starting-m-tion of the engine, its gases being pro-heated before enterinp the t'tillllflhllflllchambers wherein their explosion is also very materially fostered then-eh The derive 1 intended for UN primarily in cold weather, hot, it ean ohrioudy he llht'(l at any time or dnringvany NHHHII ol' the year, espeeiall for cold eliinateh to render the maehine more readily and quickly efli rient For speedy atarting; or advancing movement or e|'\'it 'u.

I claim An aeee sory, detaehahle warmin -attaehment for manifold of internal eom )US- tion engines. comprising an independent, auxiliarr, open-top cup adapted to contain hoth the manifold and the preliminary hotwater or other hot loosely-applied heating;- medium and having;' a lap or split joint to facilitate its removable attaelnnent in place for said accessory use, a clamping-ring adapted to iletzu-lnthly-fasten the lower (:on'

traeted end or neek ol' the said open-top cup on the upturned elhow of the manifold, a pair of hUH]wtwirnl-lUnPS to iletlaehahly-ltold the auxiliary. open-lop rup in using position. and a drainworl; in the ll'JllUlll ol' Htlltl enp. -.\t|h l:|ntiall as .-ho\\'n and desrrihed.
